I don't know if it would help you to see the list of stuff I take on a self-contained tour. Obviously you don't have the same weight concerns since you're not taking your stuff on the bike with you. But some of my thoughts might be helpful anyway.

If you're interested, I put together an article that is essentially my packing list. You can find it at http://denisepacks.crazyguyonabike.com.

Happy dreaming, and have a great trip!
